Greetings from Dallas!As the owner of 2 original Spark Controllers I was curious if they could be used to control the iPad iSpark software. I had sent this message to Arturia:

Will Spark Creative Drum Machine work with iPad iSpark App? I have the original controller not the Sparkle device. I would like this information before I purchase the APP. Thank you!

The response I received from Arturia tech support said "unfortunately no" Since the Spark and Spark LE controllers both work with the desktop software I finally decided to take a chance and purchased the iSpark App. Guess what, I am using the iPad Pro with the powered camera connector and it works great! No mapping, just plug it in and go. If there are any issues, I have not found them.
